Umbelliferone, also known as 7-hydroxycoumarin, hydrangine, skimmetine, and beta-umbelliferone, is a widespread natural product of the coumarin family.
It absorbs ultraviolet light strongly at several wavelengths. Despite several indications that this chemical is photomutagenic, it is used in sunscreens. Umbelliferone has been reported to have antioxidant properties.[medical citation needed]; It is a yellowish-white crystalline solid that has a slight solubility in hot water, but high solubility in ethanol.
